Almost Caught Cheating

I had hit up an old hookup of mine a few weeks ago to see if we could hook up sometime soon. Apparently she and my current girlfriend have a good mutual friend and hookup sent the texts to my girlfriend. I played it off as a scam. I don’t really feel bad though, I mostly just feel bad I got caught. I probably won’t stop, I’ll keep it up but not through any stuff on my phone.
